Aibo ERS-7 is a mobile robotic dog. It weights approximately 1.6kg with the following dimensions: 180 (w) * 278 (h) * 319 (d) mm. It has many different sensors (e.g. temperature, acceleration, electric static, pressure sensor, infrared, stereo microphones.). A wireless LAN connection can be established between the robot and a laptop, whereby the robot can notably send current states of its sensors every 32ms. The robot has been used extensively by Dorothée Francois as part of her PhD research. Dorothée developed an adaptive controller so that the AIBO could adapt to different play styles of children with autism. It was also used in a long-term study inspired by non-directive play therapy.
